Why do people keep wanting to hack into my ad server!?

* failed login attempts (* lockout(s)) from IP: 69.22.170.***
Last user attempted: admin
IP was blocked for * hours

It is getting really dull. So I maxed out the security options, and have secured it as best I can. It is really annoying that people keep trying to guess my password. I may have to add a second line of defence soon if this keeps happening. It happens each week pretty much, and they always try to login as ‘admin’, so it’s not accidental. "Admin" is the primary user in most WordPress installations.
